TO ALL WHOM IT MAY GOFOERN:

Be it known that we, HENRY Gross and Gnone'a S. Ynvcmwo, ct Tiflin, in the county of Seneca, and State of Ohio, have invented a new and improved Annunciator; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the some, reference being had to the accompanying-drawings forming part of this specification, in which- Figure 1 is a vertical section of our improved machine, taken through the line a; z, fig. 4.

Figure 2 is a detail sectional view of thc same, taken through the line 3 y, fig. 4.

Figure 3 is a vertical longitudinal section of the same, taken through the line 2 z, fig. 4, part being broken away to show the front plate.

Figure 4 is a top view of the same, partly in section through the front plate.

Similar. letters of reference indicate like parts.

Our invention is designedto furnish an improved annunciator, for use in hotels and other places, and it consists in the self-controlling iigure-drop, in combination with the upright'guidc upon which it slides; in the peculiarly-shaped double spring by which it is held in place, in combination with the figure-drop and with the upright guide; in raising the figure-drops by means of a. rack operated by a lever, and in the peculiarly-shaped levers, in combination with the connecting-rods and. double springs for releasing thofigure-drops, and with the.

tumbler by which the hammer-shaft is operated to strike the bell; the whole being constructed and operated as hereinafter more fully described.

A is thefront plate of the annunciator, which has openings formed through it, through which the figures or other signal-marks or notices are exhibited. B are the drops, the ends of which are turned up or have flanges formed upon them, which are notched so as to slide upon the upright guides G. The movement of the drops 13 is limited by notches, formed in the under side of the upright 0, within which the flanges of the said drops work, as shown in figs. 1 and 4. The drops Bare made twice the size of the holes through the plate A, the face of the lower half being leftblank, and the upper half having the number or other signalmark upon it. D are the double springs, by which the drops are held in position, both when down and when up. The lower ends of the springs are secured to the upright guides 0. They are slotted so as to'work upon both sides of the uprights C, and their upper ends are bent so as to form an angle, which takes hold of the upper flange of the I drops B to hold them up, and which rest upon the said upper flange, to hold the said drops steady when down. To the upper ends of the springs D are pivoted the ends of the wires E, which connect the said springs with the lovers F, so that the said springs may be raised to release the drops B by operating the said levers F. The rods E pass through holes in the lovers F, and have nuts upon their projecting ends, against which the lovers F press, to operate the springs D. The levers F are made in substantially the shape shown in fig. 1, and they are pivoted to the shaft G. H is the tumbler, extending across the'apparatus, and the ends of which are bent at right'angles, and pivoted to the same shaft, G, to which the levers F are pivoted. The tumbler His held against the shoulders of the levers F by the spring I, one end of which is attached to the side plate-J of the apparatus, and the other end of which rests against a pin attached to one of the ends of the tumbler .H, as shown in figs. 1 and 4. The other end of the tumbler H is so formed as to tal-ie hold of an arm, is, attached to the hammer-shaft K, to partially revolve it to raise the hammer.' L is a spring, oneend of which is attached to the side plate J, and the other end rests against an arm, 7: attached to the hammer-shaft, to cause the hammer to strike-the bell as soon as the arm is is released from the end of the tumbler. M is a spring, resting against the arm is of the hammer-shaft, to lift the hammer from the bell and prevent it from repeating the blow upon the rebound. By this construction and combination of parts the number or signal-mark is exhibited, and the bell-hammer operated by means of the same lever F, and at the same time. N is a rack or frame,

sliding up and down upon the guide-rod O and upon the uprights C. The rack N, when down, rests upon the inner end of the lever P, by means of which it is raised, and its horizontal bars are in such a position that the lower ends of the drops B, when down, may rest upon them. When one or more of the drops B have been lowered, and it is desired to raise them, the rack N is raised by operating the lever P, which forces up the drops so that the springs D may take hold of them and hold them raised. I

What we claim as new, and desire to secure by Letters Patent, is-- A 1. The s'elf-controlling figure-drops-B, constructed substantially as described, in combination with the upright guides C, upon which they slide, as and for the purpose set forth.

2. The double springs D, constructed substantially'as herein shown and described, in combination with the drops 13 and with the. upright guides C, as and for the purpose set forth. I

3. The levers F, constructed substantially in the form and manner herein shown and described, in combination with the connecting-rods E and double springs D, for the purpose of releasing the drops B, and with the tumbler H, by means of which the bell-hammer is operated, as and for the purposes set forth.
